Wolves' Bakary Sako has revealed he is mulling over offers from the Premier League but is yet to decide on his future.
Rotherham boss Steve Evans will decide the fate of his out-of-contract players in a meeting on Monday.
Arsenal have emerged as Sky Bet's favourites to sign Gonzalo Higuain following a run of bets on the Real Madrid striker to move to the Emirates.
Higuain is expected to leave the Bernabeu this summer after revealing his intention to leave at the end of last season, having endured a constant battle to command a consistent starting place during his six years in the Spanish capital.
Any deal would likely see Arsenal break their transfer record, which currently stands at around £15m for their acquisition of Andrei Arshavin, with Madrid expected to want around £30m.
It also remains to be seen what the intentions of Jose Mourinho's replacement will be, with PSG boss Carlo Ancelotti currently the heavy favourite to get the job.
Sky Bet Football Trader Chris Spicer said: "Widespread reports suggest that Arsenal are trailing Higuain and our punters seem convinced that Arsene Wenger will break from his stringent approach to transfer dealings and spend big.
"Juventus had been as short as 2/9 to secure his services as they look to add a prolific striker to their title winning side but are now considered second favourites in what is considered a two-way battle."
